Stability and Excitations of a Dipolar Bose-Einstein Condensate with a Vortex
Ryan M. Wilson, Shai Ronen, John L. Bohn
We study the stability of singly- and doubly-quantized vortex states of harmonically trapped dipolar Bose-Einstein Condensates (BECs) by calculating the low-lying excitations of th…
How Does a Dipolar Bose-Einstein Condensate Collapse?
J. L. Bohn, R. M. Wilson, S. Ronen
We emphasize that the macroscopic collapse of a dipolar Bose-Einstein condensate in a pancake-shaped trap occurs through local density fluctuations, rather than through a global co…
Generalized Mean Field Approach to a Resonant Bose-Fermi Mixture
D. C. E. Bortolotti, A. V. Avdeenkov, J. L. Bohn
We formulate a generalized mean-field theory of a mixture of fermionic and bosonic atoms, in which the fermion-boson interaction can be controlled by a Feshbach resonance. The theo…
Dynamical pattern formation during growth of a dual-species Bose-Einstein condensate
Shai Ronen, John L. Bohn, Laura E. Halmo +1
We simulate the growth of a dual species Bose-Einstein condensate using a Gross-Pitaevskii equation with an additional gain term giving rise to the growth. Such growth occurs durin…
Loss of molecules in magneto-electrostatic traps due to nonadiabatic transitions
Manuel Lara, Benjamin L. Lev, John L. Bohn
We analyze the dynamics of a paramagnetic, dipolar molecule in a generic "magneto-electrostatic'' trap where both magnetic and electric fields may be present. The potential energy…
Prospects for an electron electric dipole moment search in metastable ThO and ThF
Edmund Meyer, John Bohn
The observation of an electron electric dipole moment (eEDM) would have major ramifications for the standard model of physics. Polar molecules offer a near-ideal laboratory for suc…
